Term Rewriting System R:
[x]
half(0) -> 0
half(s(s(x))) -> s(half(x))
log(s(0)) -> 0
log(s(s(x))) -> s(log(s(half(x))))
Termination of R to be shown.
TRS
↳Removing Redundant Rules
Removing the following rules from R which fullfill a polynomial ordering:
log(s(0)) -> 0
where the Polynomial interpretation:
| POL(0) | = 0 |
| POL(log(x1)) | = 1 + x1 |
| POL(s(x1)) | = x1 |
| POL(half(x1)) | = x1 |
was used.
Not all Rules of R can be deleted, so we still have to regard a part of R.

↳Dependency Pair Analysis
R contains no Dependency Pairs and therefore no SCCs.
